Solids, Liquids and Gases

By Kathleen Amy

Solids• One of the major states of

matter• A solid does not take the shape

of its container• Atoms in a solid are tightly

bound together

Liquids• Second major state of matter• Liquids can flow• Liquids take the shape of their

container• Atoms in a liquid are loosely bound.

Gases• Third major state of matter• Gases have no shape or size of

their own• Gases are all around us.• Gas particles can move past

each other.

Changing of Matter• All matter can change from one

state to another.• In order for matter to change

form, it may require very low temperatures, very high temperatures, or high pressure.

• Water can be changed to a liquid when it reaches its melting point

• Water can be changed to a gas when it reaches its boiling point.
